For referencce, I'm 5'10" and between 155 and 160. I ordered a size 9 and right now I am deeply regretting waiting so long to try Kancans. They are super comfortable and look great. These are also my first pair of high waist jeans, and OMG, I don't know why I resisted. Sure, I look like my mom from 1987, but that was going to happen anyway.
